Introduction
Several NGSI-LD Context Brokers and related software modules, such as data ingestion, event processing, and
visualization, are being developed globally, reflecting the widespread adoption of NGSI-LD standards. With multiple
open-source implementations available, establishing comprehensive interoperability test cases is essential to ensure that
different brokers, even from various vendors, can operate together seamlessly. While these tests do not directly validate
the NGSI-LD specification, these tests may also be used to demonstrate whether the implementations can interoperate
effectively and whether the NGSI-LD specification should be revised to avoid ambiguity (if any). The results can be
applied in specific scenarios to highlight system compatibility, showcase cross-vendor collaboration, and provide
valuable feedback for improving overall implementation quality.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the following terms apply:
NOTE: The letters "NGSI-LD" were added to most terms to confirm that they are distinct from other terms of
similar/same name in use in other organizations, however, in the present document the letters "NGSI-LD"
are generally omitted for brevity.
NGSI-LD Central Broker: NGSI-LD Context Broker that only uses a local storage when serving NGSI-LD requests,
without involving any external Context Sources
NGSI-LD Context Broker: architectural component that implements all the NGSI-LD interfaces
NGSI-LD Context Consumer: agent that uses the query and subscription functionality of NGSI-LD to retrieve context
information
ETSI
6 ETSI GS CIM 053 V1.1.1 (2025-07)
NGSI-LD Context Producer: agent that uses the NGSI-LD context provision and/or registration functionality to
provide or announce the availability of its context information to an NGSI-LD Context Broker
NGSI-LD Context Registry: software functional element where Context Sources register the information that they can
provide
NOTE: It is used by Distribution Brokers and Federation Brokers to find the appropriate Context Sources which
can provide the information required for serving an NGSI-LD request.
NGSI-LD Context Source: source of context information which implements the NGSI-LD consumption and
subscription (and possibly provision) interfaces defined by the present document
NOTE: It is usually registered with an NGSI-LD Registry so that it can announce what kind of information it can
provide, when requested, to Context Consumers and Brokers.
NGSI-LD Distribution Broker: NGSI-LD Context Broker that uses both local context information and registration
information from an NGSI-LD Context Registry, to access matching context information from a set of distributed
Context Sources
NGSI-LD Federation Broker: Distribution Broker that federates information from multiple underlying NGSI-LD
Context Brokers and across domains
